ISAAC. RASKIN AND JAMES IPEIBJE'JTCI-IIN,l OF NEW YORK, N. Y.

BOUGE-BRAKE.

of' Russia, residing at New York, in the county of New York'and State ofNew York, have invented new and useful Im-v provements in Dough-Brakes,of which the following is a specification.

This .invention relates to dough-kneading '.machinery, and moreespecially to that kind of machine known as a dough-brake.

The object of the invention is to provide a dough-brake that will occupycomparatively little space and will deliver the dough sheet coming fromthe braking rolls back* beneath the rolls to the front of the ma-vchine, to enable the dough to be fed to the' rolls again. 4

A further object is to provide adouglr box for receiving the doughsheet, whichl box is moved forward and backward to cause the sheet vtobe received in folded con'- 'dition therein. l

A further object is to hang the dough box below the feeding surface,whereby the box may be swung up over said surface to redeliver the doughthereto. i

With these and other objects in view, as will become apparent as vthespecification proceeds, theinvention consists in the parts, arrangementsand combinations hereinafter described and in the claims moreparticularly pointed out.

Inthe drawings, showing, as illustrative, the preferred form of theinvention: Figure v1 is a side elevation of the machine', Fig. 2 is alongitudinal section therethrough; Fig. 3 is an end view; and Fig.' 4 isa transverse vertical section.

has a suitable framework, Cooperating braking rolls 11 vare mounted inand extend between these side frames. Suitable arrangements may beprovided whereby the distance between the rolls may be varied. In theconstruction illustrated, the upper roll is journaled in boxes 12, whichare mounted slidably in slots 13 in the side frames 10. rThese boxeshave internally threaded port-ions which are engaged by screws 11i.These screws are journaled in The machine thel framework and carry bevel.gears 15,

which are engaged by other bevel gears 16 on a shaft 17, which shaft isjournaled in brackets on a top frame piece 18 and. is provided with a;hand v*wheel 19. The lower roll 11 is journaled in'boxes 2O resting onthe' bottoms of the slots 13. l

No claim is made to the particularfmode of journaling and adjusting thebraking rolls.

A feed surface is provided for.conduct ing the dough to the brakingrolls 11. In the form of the invention illustrated, this feed surface isa stationary surface, but this is not essential to the invention. The parj. t-icular .embodiment of feed surface shown is a table 21, overwhich the dough may be pushed by the hand or by asuitable instrument. il

In accordance with the invention, conveying means, as shown, an apron22, is located below the' rolls 11 and-the feedI surface 21 and isar-ranged to carry the dough sheet back to the front of the machine.This apron extends sufficiently far to the rear to receive the doughsheet which'hangs down from the. .rolls at the rear thereof. As shown,the apron inclines upward toward the front. The lapron passes aboutandis carried by rbllers 23 and 24., suitably mount; ed in the frameworkof the machine;v and preferably the front roller 23 is of smalldiameter. Means, as screws 25,` may be provided for taking up slack inthe apron.

In accordance with the invention, a box 27 is provided for receiving thedough 'sheet from the apron 22. This boxis constructed and arranged toreceive the doughl sheet in folded condition and `to re-deliver it tothel table 21. In the best form of the invention, the box is hungbeneath the table and the front end of the apron by suitable hangers 28,lwhich permit the box to be swung up and inverted over the table. Invthe particular construction illustrated, the hangers 28 are supported ona cross-rod 29, which is 'received in horizontal slots 30 to slidelater'- ally backward and forward therein. These slots 30arc shown asbeing formed in verti-4 cal side boards 31 of the table 21. The box 27is shownas being movedbackward andl forward by connecting rods 32,.which are pivoted at their forward endete the cross Isuitable hand hold36,

rod 29 and at their rear ends, respectively to a crank arm 33 and awheel 34, both on a shaft 35. The box 27 is -provided with a whereby itmay be swung up over the table manually.

lThe particular form of gearing is not material tothe invention. Asshown,

shaft 37 has fast and loose pulleys 38 and wheel 46 on the shaft of theroller 24, by

means of 'a sprocket chain 47.

Braces 48 may support the forward part ofthe table 21 from the sideframes 10.

In the operation of the machine, dough is placed on the table21 andpushed between `is there collected in the'rolls 1l. It comes out at therear of these rolls in the form of a sheet and descends .upon theforward traveling apron 22,' at the forward end of which the dough sheetdescends into the reciprocating box 27 and folded condition. When allthe dough sheet isfolded into the box, the latter is swung up over thetable, and

` y, the folded sheet is deposited thereon. The

pulled forward upper edge of the-folded sheet may now be manually andinserted be- 11, which draw the sheet The operation may be retween therolls through again.

peated as often as desired, and the rolls may be adjusted toward eachother from time to time, or after each rolling, to make the sheetprogressively thinner. IVith this machine, no operator at the rea' ofthe'machine is re uired. r

scraper 49 may be adjustably mounted in rear ofthe lower roller 1l. Ashield 50 may be located in'rear of the rollers, to prevent dough beinglost at the back of the machine.

I/Vhat is claimed as` new is: 1. In a dough brake, the combination ofcooperating braking rolls, a feed surface adapted to conduct the doughtosaid rolls,

an endless traveling dough-receiving andv carrylng surface disposedbelow the rolls and thence extending forward below the feed surface andconsiderably in advance of the rolls for carrying the dough' sheet backto the front of the machine, means for driving the endless surface so asto cause itsY upper course to travel forward beneath the rolls and feedsurface, and a doughreceiv' ing surface below the forward part of saidcarrying surface and below the feed surface and adapted and'ari anged toreceive the dough sheet from the carrya driving to the front ing surfaceand 'movable up over the feed surface to redeliver the dough thereto.

2. In a dough-brake, the combination of coperating braking rolls,a'feed, surface adapted tol conduct the dough to said rolls, a'n endlesstraveling doughueceiving and carrying surface disposed below the rollsand thence extendin forward below the feed surface and considerably inadvance of the rolls for carrying the dough sheet back of the machine,means for driving the endless surface so as to cause its upper courseto-travel forward beneath the rolls and feed surface, and a box hungbelow the forward part of said carrying surface and below the feedsurface and braking rolls and adapted to receive the dough sheet fromthe carrying surface and to be swung up over said feed surface tore-deliver the dough thereto.

3. In a dough-brake, the combination of cooperating braking rolls, afeed surface -adapted to conduct the dough to said rolls,

an endless Vtr'aveling dough-receiving and carrying surface adapted andarranged to carry the dough sheet back to the frontof the` machine, areceiving surface below the forward part of said carrying surfaceadapted and arranged to receive the dough sheet from the carryingsurface, and means for moving said receiving surface back and forthduring the reception of the dough sheetthereon, whereby the dough sheetis folded thereon.

4. In a dough-brake, the combination of cooperating braking rolls, aVfeed surface adapted to conduct the dough to said rolls, an endlesstraveling dough-receiving and carrying surface beneath Said rolls andfeed surface adapted and arranged t`o carry the dough sheet back to thefront of the machine, a receiving surface below the forward part of saidcarrying surface and adapted and arranged to receive the dough sheetfrom the carrying surface, said receiving surface being movable up overthe feed surface tore-deliver the dough thereto, and means for movinsaid receiving surface back and forth during the reception of the doughsheet thereon whereby the dough is received in folded condition.

5. In a dough-brake, the combination of braking rolls adapted to delivera continuous sheet of dough, a receiving surface adapted to receive thedough sheet after coming from said rolls, andpmeans for reciprocatingthe receiving surface in place so as to cause the sheet tobe receivedthereon in a folded pile, said receiving surface being movable todeliver said folded pile in position to pass again through the rolls.

6. In a dough-brake, the combination of braking rolls, a receivingsurface adapted to receive the dough sheet after coming from 'to beswung up said rolls, means or `ree'lprioeetrlg thereceiving surface 1nplaceeo as to cause the sheet to be received thereon in a folded pile,and a, pvoted hanger supporting said rece'lvng surface and enabling saidsurface to deliver the folded sheet for' another passage through therolls.
